| Abstract |
Partial replacement of feed protein with shrimp waste meal was done in four experimental diets for Nile tilapia fly (Oreochromis niloticus L.) at 0. 10,20 and 30% substitution levels (T1,. T2. T3 and T4, respectively). The experimental diets were applied for 180 tilapia each of 1.4 g initial weight which were stocked randomly in to 12 aerated aquaria (60 x 40 x 30 cm) during the experiment period of 64 days.
Results indicated that, chemical analysis of shrimp meal showed that it contains high percentages of CP (49%) and ash (26.35); however. it contains low contents of EE (3.32%), CF (10.48%) and NFE (10.85%).
Also, the final weight of Nile tilapia decreased significantly (P < 0.05) with increasing shrimp meal level in the tested diets up to 30% as a replace of feed protein. The results showed that the highest weight gain. SGR, PER. PPV and EU% was achieved with T1 T2 and T3 compared with T4
In conclusion, shrimp meal from the nutritionally and economically points of view is a non-conventional animal protein source in Nile tilapia feeding up to 20% of feed protein.
